3 Claims.

The present-invention relates to new and useful improvements in gas heaters of the radiant type and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character comprising a construction and arrangement which is such that a uniform distribution of the gas over substantially the entirearea of the heater will be had, thus materially promoting eificiency and economy.

Another very important object of the invention is to provide a heater of the aforementioned character embodying novel means whereby the radiants may be conveniently adjusted as desired toward or away from the flames. I

Other objects of the invention are to provide a heater of the character described which will be comparatively simple in construction, strong, durable, attractive in appearance, reliable and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with .the accompanying drawings wherein like characters of reference 25 designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in front elevation of a heater constructed in accordance with the present invention.

Figure 2 is a view in vertical section through the device, taken substantially on the line 2-2 of Fig. 1.

Figure 3 is a vertical sectional view, taken substantially on the line 3-3 of Fig. 4.

35 Figure 4 is a view in front elevation of the burner.

Figure 5 is a top plan view of the adjustable radiant support or carriage, an end portion thereof being broken away.

Figure 6 is a cross sectional view through the radiant support or carriage.

Figure '7 is a view in horizontal section through one of the radiants.

Figure 8 is a view showing the means/for ad- 4,5 justably supporting a radiantcarriage or support.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises an open 50 front metallic casing which is designated general- 1y by the reference numeral I, said casing including a hollow base portion 2 which is provided with suitable supporting legs 3. Mounted vertically in the casing I is a panel or partition 4 of 65 suitable heat insulating material.

Also mounted in the casing I is a burner unit which is designated generally by the reference numeral 5. The burner unit 5 comprises a manifold 6 which is mounted horizontally in the upper portion of the base 2. Extending into the base 2 from One end thereof and connected at an intermediate point to the manifold 6 is a supply pipe I. Rising from the manifold 6 and extending vertically in the casing I adjacent the front of the panel 4 is a series of spaced branch pipes 8 having formed therein spaced discharge ports 9. Of course, the gas discharge ports 9 are in the front portions of the branch pipes 8.

Referring now to Fig. 8 of the drawings, it will be seen that lugs ID or the like rise from the base 2 in the end portions of the casing I. Mounted horizontally on the lugs I0 are rods l I. The reference numeral l2 designates an adjustable radiant support which is shiftably mounted on the rods II. Ears [3 which depend from the end portions of the radiant support I2 are slidable on the rods I I.

Rising from the base 2 at an intermediate point is a pair of lugs or the like l4. Rotatably mounted in the elements I4 is a screw shaft l5 which is provided, on one end, with an operating knob I6. Depending from the radiant support I2 is a pair of ears I! which are threadedly engaged with the screw shaft I5.

Rising from the support l2 are opposed flanges l8 which, in conjunction with each other, define channels or grooves I9 for the reception of the lower end portions of a series of radiants 20. As best seen in Fig. 7 of the drawings, the radiants 20 are substantially U-shaped in horizontal section. In the embodiment shown, the radiants 20 are provided with a plurality of vertical slots 2!, also with circular openings 22 in their upper end portions. The radiants 20 also have formed therein integral vertical ribs 23 from which integral conical spreaders 24 project. The spreaders 24 are aligned with the ports 9 of the burner 5.

It will thus be seen that a construction and arrangement has been provided whereby the gas will be uniformly discharged in a large number of jets over substantially the entire area of the burner in a manner to materially promote efficiency in addition to bringing the radiants 20 to a uniform glow from top to bottom thereof. By simply rotating the screw shaft l5 through the medium of the knob N3 the radiants 20 may be conveniently adjusted as desired toward or away from the jets of flame. These jets of flame strike the substantially conical elements 24 and are spread in all directions thereby thus further promoting efficiency and economy. Of course, the invention may be used in conjunction with any other types of burners and heaters for which it may be found adapted and desirable, such as in domestic cooking stoves, basement and floor gas furnaces, glass furnaces, etc.

It is believed that the many advantages of a radiant gas burner constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

1. A heater of the class described comprising a casing, a vertical partition in the casing, a gas burner mounted in the casing and including a manifold and further including a plurality of vertical perforated branches rising from the manifold adjacent the partition in the :casing, a plurality of radiants movably mounted in the casing, and means for adjusting said radiants toward and away from the manifold branches.

2. A burner of the class described comprising a casing, a gas burner mounted in the casing and including a series of vertical perforated pipes, a support shiftably mounted in the casing and movable toward and away from said perforated pipes,

a plurality of radiants mounted on said support 5 in opposed relation to the perforated pipes, and manually operable means for shifting the support for adjusting the radiants toward or away from the perforated pipes.

3. A heater of the class described comprising a 10 casing open at its front, a burner including a series of spaced, perforated pipes mounted vertical'ly in the casing, a pair of rods mounted horizontally in the casing, a support slidably mounted on said rods and movable toward and away from 15 the perforated pipes, a plurality of radiants mounted on the support in spaced, opposed relation to the perforated pipes, said support includ- I WALTER HAMIV IICK.
